I have a table called calls and I need a single search input, to search in two columns, contact_number and contact_name.
How do I do this on Yii2?
_search.php
$form->field($model, 'searchstring')->textInput(['placeholder' => 'Search']);
common\models\CallsSearch.php
[['searchstring'], 'safe']
(..)
$query->orFilterWhere(['like', 'searchstring', $this->contact_name])
->orFilterWhere(['like', 'searchstring', $this->contact_number]);
controllers\CallsController.php
public function actionIndex()
{
$searchModel = new CallsSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
Well you are trying to use the search_string input to filter 2 fields contact_name or contact_number but you are not using it to compare with the fields, you are specifying the custom model attribute as table_column, which is wrong, you should change the search model code to the following
$query->andFilterWhere ( [ 'OR' ,
[ 'like' , 'contact_name' , $this->search_string ],
[ 'like' , 'contact_number' , $this->search_string ],
] );
Hope it helps.

To show my GridView I use this ActiveDataProvider:
public function search($params)
{
$query = PublicationsPublication::find()
->select(['eid', 'title', 'pubdate', 'citedby', "STRING_AGG(DISTINCT(CONCAT(author.authid, ' - ', authname)), ', ') AS authors"])
->joinWith('publicationsAuthor')
->groupBy(['eid','title','pubdate','citedby']);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
$this->load($params);
if (!$this->validate()) {
return $dataProvider;
}
...
}
I can't figure out how to use the column generated by the STRING_AGG() function in the Gridview.
Just in case is needed, the publicationsAuthor relation is coded this way:
public function getPublicationsAuthor() {
return $this->hasMany(PublicationsAuthor::className(), ['authid' => 'authid'])
->viaTable('publications.pub_author', ['pubid' => 'id']);
}
I need to use the STRING_AGG() function because I want to show many authors in one cell of the Gridview.
I tried to use the "authors" column in this way:
$gridColumns = [
[
'class' => 'kartik\grid\SerialColumn',
'width' => '20px',
],
'eid',
'title',
'pubdate',
'citedby',
'authors',
];
echo GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => $gridColumns,
'pager' => [
'firstPageLabel' => 'First',
'lastPageLabel' => 'Last'
],
...
]);
But unfortunately it didn't work. In the Grid all the values are set to "not set". The query works great because I tested it in PgAdmin.
yii\data\ActiveDataProvider works with models so only fields defined by model are available by default. The easiest way to add field generated by some expression is to add public property with same name to your model like this:
class PublicationsPublication extends ActiveRecord
{
public $authors;
// ... other code in PublicationsPublication model ...
public function attributeLabels()
{
// You can also add label for new field
return [
'authors' => 'Authors',
// ... other labels ...
];
}
}
The public property $authors will be loaded with data from field authors in the result of your SQL query. Then you can use it in grid as any other field.
The other option is to use yii\data\SqlDataProvider instead of yii\data\ActiveDataProvider.
Guys, i'm very new at it, so please hep me.
This is my SQL:
SELECT tb1.login, tb2.user
FROM tb1
INNER JOIN tb2 ON tb1.login = tb2.user
I dont get how to make it in query, so i could show values in GridView.
I did it but it doesnt work at all.
$query = TB1::find()->select(['tb1.login', 'tb2.user'])
->innerWith(TB2::tablename(), 'tb1.login = tb2.user');
return new ActiveDataProvider([
'query' => $query
]);
My GridView
GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
[
'attribute' => 'tb1.login',
],
[
'attribute' => 'tb2.user',
}
],
],
]);
After i check my gridview is says that "not set", please help me!
Im veeeery new at it, im sorry
The "correct" way how to handle this use case is using relation methods (https://www.yiiframework.com/doc/guide/2.0/en/db-active-record#relational-data)
So you should define a method "hasXXX" (based on your relation) in the TB1 and then you can access it in the GridView using `value' option
[
'attribute' => 'packageName', // it has to be defined in the model
'value' => function (Contract $model) {
return $model->package->name;
},
]
Yii2 will handle the SQL and everything...
OR
you can just add public property $publicName and $userName in the TB1 model and set the ALIAS in your SQL select(['tb1.login AS loginName', 'tb2.user AS userName']). But I consider it as quick&dirty solution.
To help you along a bit more explicitly:
In the tb1 model add the following join function:
public function getTable2(){
return $this->hasOne(Tb2ModelNameHere::className,['tbl2_id'=>'tbl1_fk_id']);
}
where 'tbl2_id' and 'tbl1_fk_id' are the fields that connect table 2 and 1 respectively
Within the Gridview, you can simply call the join and it handles the query:
GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'login', // presuming login is an attribute of tbl1
'table2.field_name_here',
// or
[
'attribute' => 'table2.field_name_here',
],
],
]);
The code above assumes:
That the DataProvider is from Table1. The function "getTable2" must be located in the model of the current dataProvider. In other words: the dataProvider is from Table1 and withhin the Table1 model, we have added the function "getTable2"
To call the function "getTable2" we use "table2" in the attribute of the gridview. Yii automatically adds the "get" and automatically capitalises the first letter. Hence "table2.user_name" will call the join function "getTable2" and retrieve the user_name field from Table2
TL;DR
I have a query that works in RAW SQL but i have had little success recreating it with query builder or active record.
I am working on a web application based off of the yii2 advanced application template. I have written a database query and implemented it with findbysql() returning the correct records but am having trouble translating this into active record.
I originally wanted to allow the user to modify (filter) the results by means of a search form(user & date), however i have since realized that implementing filters on the gridview with active records would be smoother.
I have gotten simple queries to work however am unsure of how to implement one with this many joins. Many examples used sub queries but my attempts failed to return any records at all. I figured before I attempt filters i need to transcribe this query first.

i will assume, based on the question you asked here you liked in comments that you provided the entire query
(no other fields, that you took out just to show sample code)
therefore, if you only need only the fields specified in SELECT statement, you can optimize your query quite a bit:
first off, you're joining with host_machines only to link cameras and events, but have the same key host_machines_idhost_machines on both, so that's not needed, you can directly:
INNER JOIN events events
ON (events.host_machines_idhost_machines =
cameras.host_machines_idhost_machines))
secondly, the join with ispy.staff, the only used field is idreceptionist in WHERE clause, that field exists in events as well so we can drop it completly
the final query here:
SELECT videos.idvideo, videos.filelocation, events.event_type, events.event_timestamp
FROM videos videos
INNER JOIN cameras cameras
ON videos.cameras_idcameras = cameras.idcameras
INNER JOIN events events
ON events.host_machines_idhost_machines =
cameras.host_machines_idhost_machines
WHERE (events.staff_idreceptionist = 182)
AND (events.event_type IN (23, 24))
AND (events.event_timestamp BETWEEN videos.start_time
AND videos.end_time)
should output the same records as the one in your question, without any identitcal rows
some video duplicates will still exists due to one to many relation between cameras and events
now to the yii side of things,
you have to define some relations on the Videos model
// this is pretty straight forward, `videos`.`cameras_idcameras` links to a
// single camera (one-to-one)
public function getCamera(){
return $this->hasOne(Camera::className(), ['idcameras' => 'cameras_idcameras']);
}
// link the events table using `cameras` as a pivot table (one-to-many)
public function getEvents(){
return $this->hasMany(Event::className(), [
// host machine of event => host machine of camera (from via call)
'host_machines_idhost_machines' => 'host_machines_idhost_machines'
])->via('camera');
}
the VideoController and the search function itself
public function actionIndex() {
// this will be the query used to create the ActiveDataProvider
$query =Video::find()
->joinWith(['camera', 'events'], true, 'INNER JOIN')
->where(['event_type' => [23, 24], 'staff_idreceptionist' => 182])
->andWhere('event_timestamp BETWEEN videos.start_time AND videos.end_time');
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
return $this->render('index', [
'dataProvider' => $dataProvider,
]);
}
yii will treat each video as a single record (based on pk), that means that all video duplicates are
removed. you will have single videos, each with multiple events so you wont be able to use 'event_type'
and 'event_timestamp' in the view but you can declare some getters inside Video model to show that info:
public function getEventTypes(){
return implode(', ', ArrayHelper::getColumn($this->events, 'event_type'));
}
public function getEventTimestamps(){
return implode(', ', ArrayHelper::getColumn($this->events, 'event_timestamp'));
}
and the view use:
<?= GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'idvideo',
'eventTypes',
'eventTimestamps',
'filelocation',
//['class' => 'yii\grid\ActionColumn'],
],
]); ?>
edit:
if you want to keep the video duplicates, declare the two columns from events inside Video model
public $event_type, $event_timestamp;
keep the original GridView setup, and add a select and indexBy this to the query inside VideoController:
$q = Video::find()
// spcify fields
->addSelect(['videos.idvideo', 'videos.filelocation', 'events.event_type', 'events.event_timestamp'])
->joinWith(['camera', 'events'], true, 'INNER JOIN')
->where(['event_type' => [23, 24], 'staff_idreceptionist' => 182])
->andWhere('event_timestamp BETWEEN videos.start_time AND videos.end_time')
// force yii to treat each row as distinct
->indexBy(function () {
static $count;
return ($count++);
});
update
a direct staff relation to Video is currently somewhat problematic since that is more than one table away from it.
there's an issue about it here
however, you add the staff table by linking it to the Event model,
public function getStaff() {
return $this->hasOne(Staff::className(), ['idreceptionist' => 'staff_idreceptionist']);
}
that will allow you to query like this:
->joinWith(['camera', 'events', 'events.staff'], true, 'INNER JOIN')
Filtering will require some small updates on the controller, view and a SarchModel
here's a minimal implementation:
class VideoSearch extends Video
{
public $eventType;
public $eventTimestamp;
public $username;
public function rules() {
return array_merge(parent::rules(), [
[['eventType', 'eventTimestamp', 'username'], 'safe']
]);
}
public function search($params) {
// add/adjust only conditions that ALWAYS apply here:
$q = parent::find()
->joinWith(['camera', 'events', 'events.staff'], true, 'INNER JOIN')
->where([
'event_type' => [23, 24],
// 'staff_idreceptionist' => 182
// im guessing this would be the username we want to filter by
])
->andWhere('event_timestamp BETWEEN videos.start_time AND videos.end_time');
$dataProvider = new ActiveDataProvider(['query' => $q]);
if (!$this->validate())
return $dataProvider;
$this->load($params);
$q->andFilterWhere([
'idvideo' => $this->idvideo,
'events.event_type' => $this->eventType,
'events.event_timestamp' => $this->eventTimestamp,
'staff.username' => $this->username,
]);
return $dataProvider;
}
}
controller:
public function actionIndex() {
$searchModel = new VideoSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('test', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
and the view
use yii\grid\GridView;
use yii\helpers\ArrayHelper;
echo GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'idvideo',
'filelocation',
[
'attribute' => 'eventType', // from VideoSearch::$eventType (this is the one you filter by)
'value' => 'eventTypes' // from Video::getEventTypes() that i suggested yesterday
// in hindsight, this could have been named better, like Video::formatEventTypes or smth
],
[
'attribute' => 'eventTimestamp',
'value' => 'eventTimestamps'
],
[
'attribute' => 'username',
'value' => function($video){
return implode(', ', ArrayHelper::map($video->events, 'idevent', 'staff.username'));
}
],
//['class' => 'yii\grid\ActionColumn'],
],
]);
My recommendation would be to have 2 queries. The first one to get the ids of the videos that fit your search, the second query theone that uses those ids and feeds your $dataProvider.
use yii\helpers\ArrayHelper;
...
public function actionIndex()
{
// This is basically the same query you had before
$searchResults = Videos::find()
// change 'id' for the name of your primary key
->select('id')
// we don't really need ActiveRecord instances, better use array
->asArray()
->innerJoin('cameras', 'videos.cameras_idcameras = cameras.idcameras')
->innerJoin('host_machines', 'cameras.host_machines_idhost_machines = host_machines.idhost_machines')
->innerJoin('events', 'events.host_machines_idhost_machines = host_machines.idhost_machines')
->innerJoin('staff', 'events.staff_idreceptionist = staff.idreceptionist')
->where('staff.idreceptionist = 182')
->andWhere(['events.event_type' => [23,24]])
->andwhere(['between', 'events.event_timestamp', 'videos.start_time', 'videos.end_time'])
// query the results
->all();
// this will be the query used to create the ActiveDataProvider
$query = Videos::find()
// and we use the results of the previous query to filter this one
->where(['id' => ArrayHelper::getColumn($searchResults, 'id')]);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
return $this->render('index', [
'dataProvider' => $dataProvider,
]);
}
I'm trying display and filter data which I got via SQL SUM operator.
I have 2 table employee and department. Table employee contains department_id filed and salary filed. I need display all department and total SUM salary for every department.
I followed this guide, but GridView does not display any data.
Here is action:
public function actionIndex()
{
$searchModel = new DepartmentFrontendSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index',
[
'dataProvider' => $dataProvider,
'searchModel' => $searchModel,
]
);
}
Model:
class DepartmentFrontendSearch extends DepartmentFrontend
public $employee_count;
public $salary;
public function rules() {
return [
[['employee_count','salary','name'], 'safe']
];
}
public function search($params) {
$query = DepartmentFrontend::find();
$subQuery = Employee::find()
->select('department_id, SUM(salary) as salary_amount')
->groupBy('department_id');
$query->leftJoin(['salarySum' => $subQuery], 'salarySum.department_id = id');
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
$dataProvider->setSort([
'attributes' => [
'name',
'salary'
]
]);
$this->load($params);
if (!$this->validate()) {
return $dataProvider;
}
$query->andFilterWhere(['like', 'name', $this->name]);
$query->andWhere(['salarySum.salary_amount' => $this->salary]);
return $dataProvider;
}
GRID:
echo GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'salary_amount',
'employee_count',
'name',
],
]);
So, can anybody tell me what I did wrong?
If You need a filter for the alias salary_amount you should add a specific var for this (do the fact salary_amount is an alias for sum(salary) the var $salary is not useful)
public $employee_count;
public $salary;
public $salary_amount;
otherwise use salary as alias too
the in your filter you are using
$query->andWhere(['salarySum.salary_amount' => $this->salary]);
But salary_amount is the result of an aggregation so you should use having(SUM(salary) = $this->salary_amount)
$query->having('SUM(salary) = ' . $this->salary_amount);
i am need to sort some fields (asc,desc) in GridView, but same fields are calculated. Look at code below:
SearchModel:
class ObjectSearch extends Object {
use SearchModelTrait;
public function rules()
{
return [
['id', 'integer', 'min' => 1],
];
}
public function search($params)
{
$this->company_id = \Yii::$app->user->identity->companyId;
$query = Object::find()->where(['company_id' => $this->company_id]);
$dataProvider = new ActiveDataProvider([
'query' => $query,
'pagination' => false,
]);
$dataProvider->setSort([
'attributes' => [
'id',
'name',
'lastReportResult' => [
'asc' => ['lastReportResult' =>SORT_ASC ],
'desc' => ['lastReportResult' => SORT_DESC],
'default' => SORT_ASC
],
'reportPercentDiff'
]
]);
if (!($this->load($params,'ObjectSearch') && $this->validate())) {
return $dataProvider;
}
$this->addCondition($query, 'id');
return $dataProvider;
}
Methods in Object model:
public function getLastReportResult()
{
$lastReport = $this->getLastReport();
$message = 0;
if (!empty($lastReport)) {
$statistic = new ReportStatistic($lastReport);
$message = $statistic->getPercent();
}
return $message;
}
/**
* #return int
*/
public function getReportPercentDiff()
{
$lastReport = $this->getLastReport();
$message = 0;
if (!empty($lastReport)) {
$statistic = $lastReport->getReportDiff();
if (!empty($statistic['diff'])) {
$message = $statistic['diff']['right_answers_percent_diff'];
} elseif (!empty($statistic['message'])) {
$message = $statistic['message'];
}
}
return $message;
}
So, by this methods, i am calculating a values of two fields, which are need's sorting. This way doesn't working, i have a Database Exception, because object table hasn't this fields. exception
How to do sorting of this fields ?
Update: I am the author of this answer and this answer is not accurate. Preferred way is to use database view
Add two public properties to ObjectSearch.php and mark it as safe
class ObjectSearch extends Object {
use SearchModelTrait;
public $lastReportResult, $reportPercentDiff;
public function rules()
{
return [
['id', 'integer', 'min' => 1],
[['lastReportResult', 'reportPercentDiff'], 'safe']
];
}
public function search($params)
{
$this->company_id = \Yii::$app->user->identity->companyId;
$query = Object::find()->where(['company_id' => $this->company_id]);
$dataProvider = new ActiveDataProvider([
'query' => $query,
'pagination' => false,
]);
$dataProvider->setSort([
'attributes' => [
'id',
'name',
'lastReportResult' => [
'asc' => ['lastReportResult' =>SORT_ASC ],
'desc' => ['lastReportResult' => SORT_DESC],
'default' => SORT_ASC
],
'reportPercentDiff' => [
'asc' => ['reportPercentDiff' =>SORT_ASC ],
'desc' => ['reportPercentDiff' => SORT_DESC],
'default' => SORT_ASC
],
]
]);
if (!($this->load($params,'ObjectSearch') && $this->validate())) {
return $dataProvider;
}
$this->addCondition($query, 'id');
return $dataProvider;
}
Then in index.php (view file in which you are having grid view) add lastReportResult and reportPercentDiff in array of all attributes (list of all attributes ob Object model)
...
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
// your other attribute here
'lastReportResult',
'reportPercentDiff',
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
...

Though this is an old thread, stumbled upon this and tried to find other method to achieve sorting of purely calculated field to no avail... and this post unfortunately is not an answer as well... It just that I feel the need to post it here to give a heads up to those that still looking for the solution so as not to scratch their heads when trying the solution given and still fail.
The given example from documentation or referred links as far as I have tested only works if you have a column within the database schema (whether in the main table or the related tables). It will not work if the virtual attribute/calculated field you create is based on calculating (as an example multiplication of 2 column on the table)
e.g:
table purchase: | purchase_id | product_id | quantity |
table product: | product_id | unit_price |
then, if we use a virtual attribute 'purchase_total' for model 'purchase' which is the multiplication of quantity and unit_price (from the join table of purchase and product on product_id), eventually you will hit an error saying 'purchase_total' column can not be found when you tried to sort them using the method discussed so far.
